This is a handy field book, keying out the native plant genera found in the eastern United States, along with many cultivated genera.
Additions to the Flora of West Virginia
While collecting plants for a survey of the vascular plants of Morehouse parish (a M.S. thesis project of the junior author), one plant with about 50 stems of Salix tristis was found.
The authors would like to amend their list (In Castanea 42: 116-119) of state and county records, based on Radford, Ahles and Bell’s 1968 Manual of the Vascular Flora of the Carolinas, to correspond with the current updated records of Dr. J. Dan Pittillo of Western Carolina University.
An examination of two publications (Bright, 1930; Tuckerman, 1843), dealing with the genus Carex, revealed two necessary nomenclatural corrections. In both cases these deal with a species name having an earlier and valid publication by a different author from the one recognized in current Carex literature.
In January 1973, when the Flora North America Program was suspended for lack of funds, work was well underway on a revision of the “Provisional Checklist of Species for Flora North America,” issued in September 1972 as FNA Report 64.
Abandonment of the Benson Channel by the Kentucky River during the Pliocene created an extensive area of flat, poorly-drained land near Alton, Anderson County, Kentucky. The forest presently occupying the Benson Channel in the vicinity of Alton is unlike any previously reported for the Inner Blue Grass Region, and is strikingly similar to the forests of the Illinoian till plains of southwestern Ohio. The two dominant tree species are Acer rubrum and Quercus palustris. Important associated trees include Fagus grandifolia, Liquidambar styraciflua, Q. alba, Q. bicolor, Q. velutina, Nyssa sylvatica, and Fraxinus americana. The shrub and herb composition reflects the hydro-mesophytic nature of the forest and environs. The spotted salamander, Ambystoma maculatum, is reported for the first time for the Inner Blue Grass Region.
The submerged vegetation of Lake Pontchartrain, in southeast Louisiana, was surveyed before and after the April 1973 opening of the Bonnet Carre’ Spillway. Abundant species were Vallisneria americana Michaux., Ruppia maritima L., and Najas guadalupensis (Sprengel) Magnus. Potamogeton perfoliatus L. was recorded only near Point aux Herbes and Zannichellia palustris L. only in North Pass. Floating and nonrooted submerged species were noted throughout the lake but were not recorded at each survey area. The study revealed approximately 2,000 acres of waterbottom covered with submerged vegetation, the greater portion of which was recorded between Green Point near Mandeville, and Big Point near Slidell, along the northeastern shoreline of the lake. In general, similar abundance values were recorded in both surveys for submerged vegetation along the northeast shoreline. The release of fresh river water did not have observable effects on the submerged vegetation.
Two dimensional thin layer chromatographic studies of Sarracenia L. petal extracts are reported for the first time. These are correlated with leaf extract chromatography (paper) by another author, and with other factors and problems in this genus. The author agrees that chromatographic studies by themselves are of little help in phyletic and phenetic studies in Sarracenia, except in some cases where they may be considered with other characters and factors. Petal extract chromatography did disclose that red-flowered species of the genus do have masked, underlying yellow and sometimes blue pigments which would presumably be visible to bee pollinators.
